Russia’s Stealth Capabilities In 2026: Is The Su-57 Felon Reshaping Modern Air Combat?
As of July 28, 2026, the Russian Federation maintains a specialized but growing fleet of stealth aircraft, centered primarily on the Sukhoi Su-57, known by its NATO reporting name "Felon." While the journey from prototype to serial production faced numerous industrial hurdles over the last decade, the United Aircraft Corporation (UAC) has successfully accelerated deliveries to the Russian Aerospace Forces (VKS) to meet modern frontline requirements. Russia remains one of only three nations—alongside the United States and China—to have domestically designed, manufactured, and deployed a 5th-generation fighter with low-observable characteristics.
| Platform | NATO Codename | Status (July 2026) | Primary Role |
|---|---|---|---|
| Su-57 | Felon | Operational / Serial Production | Multi-role Air Superiority |
| S-70 Okhotnik-B | N/A | Testing / Early Integration | Stealth Strike UCAV (Loyal Wingman) |
| Su-75 Checkmate | N/A | Prototype / Ground Testing | Light Tactical Stealth Fighter |
| PAK DA | Messenger | In Development | Strategic Stealth Bomber |
Context and Technical Evolution of Russian Stealth
The foundation of Russia’s stealth program began with the PAK FA program, which eventually birthed the Su-57. Unlike the American F-22 Raptor, which prioritizes extreme "all-aspect" stealth, the Su-57 was designed with a focus on "front-sector" stealth, high maneuverability, and powerful sensor suites. By 2026, the VKS has moved beyond the initial small batches of aircraft, with several dozen units now active across various military districts.
A critical turning point for the platform was the successful integration of the Izdeliye 30 (Second-Stage) engine. This powerplant provides the Su-57 with "supercruise" capabilities—the ability to fly at supersonic speeds without using fuel-heavy afterburners—while further reducing the aircraft's thermal signature. Furthermore, the use of radar-absorbent materials (RAM) and internal weapons bays allows the Su-57 to operate in highly contested environments where older 4th-generation jets like the Su-35 would be vulnerable to modern surface-to-air missiles.
Beyond manned fighters, Russia has aggressively pursued unmanned stealth technology. The S-70 Okhotnik-B (Hunter) represents a significant leap in "loyal wingman" doctrine. This flying-wing drone is designed to fly alongside the Su-57, acting as a remote sensor node and weapons carrier, allowing the manned pilot to remain at a safer distance while the stealthy drone penetrates deep into enemy radar coverage.
Strategic Impact and Global Security Implications
The presence of stealth planes in the Russian arsenal has forced a reassessment of air defense strategies across Europe and Asia. For NATO, the Su-57 represents a "peer-level" threat that requires the constant presence of F-35 Lightning II and F-22 squadrons to maintain an edge. The stealth capabilities of the Su-57, combined with its N036 Byelka radar system, allow it to track and engage multiple targets while remaining difficult to lock onto at long ranges.
In the current geopolitical climate of 2026, these aircraft serve as a primary tool for "A2/AD" (Anti-Access/Area Denial). By deploying stealth assets, the Kremlin aims to project power into regions where traditional radar might otherwise offer an early warning. The tactical utility of these planes extends to:
- Suppression of Enemy Air Defenses (SEAD): Using low-observability to take out high-value radar installations.
- Maritime Strike: Utilizing internal bays to carry stealthy anti-ship missiles against carrier strike groups.
- Psychological Deterrence: Projecting the image of a high-tech military capable of matching Western technological standards.
However, international analysts continue to monitor the "stealth quality" of Russian planes. While the Su-57 is significantly stealthier than its predecessors, its radar cross-section (RCS) is generally estimated to be higher than that of the F-22, leading to ongoing debates regarding its effectiveness in a direct "stealth vs. stealth" dogfight.

What's Next for the Russian Stealth Program
Looking toward the remainder of 2026 and into 2027, the focus of the Russian defense industry is shifting toward the Su-75 Checkmate. This single-engine stealth fighter is marketed as a cost-effective alternative for nations that cannot afford the Su-57 or are barred from purchasing the American F-35. Flight testing schedules for the Checkmate are a high priority for Rosoboronexport as they seek to secure foreign investment for final production.
Additionally, the development of the PAK DA (Prospective Aviation Complex for Long-Range Aviation) remains the ultimate goal for the Russian strategic triad. This subsonic flying-wing bomber is intended to eventually replace the aging Tu-95 Bear and Tu-160 Blackjack fleets. While the project remains shrouded in secrecy, satellite imagery and industrial reports suggest that a full-scale prototype is nearing completion, which would mark Russia’s entry into the elite club of stealth-bomber-operating nations.
The integration of Artificial Intelligence (AI) in the Su-57 cockpit is also a major milestone for this year. The goal is to reduce pilot workload by automating defensive maneuvers and sensor fusion, effectively turning the pilot into a "battle manager" for a swarm of S-70 drones. As these technologies mature, the definition of Russian air power continues to evolve from sheer numbers to sophisticated, low-observable precision.
